Technical Field

Background
Existing fuel cell car on-board hydrogen system emergency hydrogen gas discharge devices generally include a TPRD (temperature controlled pressure relief valve) secured to a hydrogen storage bottle valve or tail valve. Because the emergency release device of the TPRD of the hydrogen storage bottle is generally fixed on the bottle valves or the tail valves at two ends of the hydrogen storage bottle, only high temperature from the inside of the hydrogen storage bottle or two ends of the hydrogen storage bottle can be sensed, if the bottle body part (such as the middle part of the hydrogen storage bottle) of the fuel cell automobile hydrogen storage bottle suddenly receives flame or high temperature from the whole automobile, the TPRD cannot sense and release hydrogen timely, carbon fibers on the hydrogen storage bottle can be ablated, the hydrogen storage bottle is damaged, and the risk of explosion of the hydrogen storage bottle or the automobile is seriously caused. In this regard, the conventional solution is to add a TPRD device in the middle of the hydrogen storage bottle body and introduce hydrogen gas in the hydrogen storage bottle into the TPRD device. However, a high-pressure hydrogen pipeline is additionally added, so that the complexity of a high-pressure pipeline system of the vehicle-mounted hydrogen system is increased, and the safety is reduced; moreover, the hydrogen in the high-pressure hydrogen pipeline connected with the TPRD is not controlled by an electromagnetic valve or a manual closing valve on a bottle valve, once leakage is prevented from being cut off, and the safety risk is high.

The temperature control pressure release valve comprises an air inlet channel 1.6, an air outlet channel 1.4, a trigger channel 1.7, a trigger tip hard object 1.1, and a plug and a glass bubble 1.3 positioned between the air inlet channel 1.6 and the air outlet channel 1.4, wherein one end of the trigger channel 1.7 is the glass bubble 1.3, the trigger tip hard object 1.1 is positioned in the trigger channel 1.7, and the tip of the trigger tip hard object 1.1 faces the glass bubble 1.3. The high-pressure gas line 6 is used to connect the gas generator 5 with the triggering channel 1.7. The measuring sensor 4 is used for measuring the temperature of the bottle body of the hydrogen storage bottle 3 and/or other parameter information related to fire and explosion, and when the measured temperature is greater than a set threshold value or other parameter information is greater than the set threshold value, the gas generator 5 is triggered to work when explosion risk exists. In the temperature control pressure release valve, an air inlet channel 1.6 and an air outlet channel 1.4 are mutually perpendicular, a glass bulb 1.3 is arranged at the intersection of the air inlet channel 1.6 and the air outlet channel 1.4, and the plugs comprise an upper plug 1.5 and a lower plug 1.2; in the direction of the air inlet channel, the upper plug 1.5 and the lower plug 1.2 are respectively positioned at two sides of the glass bulb 1.3. The gas generated by the gas generator 5 enters the trigger channel 1.7 through the high-pressure gas pipeline 6, the trigger tip hard object 1.1 is pricked to the glass bubble 1.3 at the tip under the action of the high-pressure gas, the glass bubble 1.3 is pricked under the action of the high pressure, and the temperature control pressure release valve is triggered to release pressure urgently.
In the present embodiment, the measuring sensor 4 may be a temperature sensor and/or a flame sensor, but in other embodiments other sensors may be used.
As an implementation of the present embodiment, the measurement sensor 4 may be installed at the middle of the hydrogen storage bottle 3 to monitor the temperature or flame received at the middle of the hydrogen storage bottle 3. Of course, in other embodiments, it may be mounted in other locations.
In this embodiment, the hydrogen storage system emergency release device further includes a triggering circuit electrically connected to the gas generator 5 and the measurement sensor 4, respectively, and the triggering circuit triggers the gas generator 5 to operate based on measurement information of the measurement sensor 4.
